One part by weight of methoxycarbonyl isocyanate was added gradually with stirring to a solution of 2 parts by weight of 2-amino-5-chlorobenzothiazole in 100 parts by weight of methylene chloride and 50 parts by weight of ethyl ether. After stirring the reaction mixture at room temperature overnight, a product was isolated by filtration giving an 85% yield of methyl 4-(5-chlorobenzothiazol-2-yl)allophanate having a melting point of 395°.
